Title:
ENABLER OF LARGE RAMAN GAIN ON SMALL EFFECTIVE AREA FIBERS
Document Type and Number:
WIPO Patent Application WO2002088782
Kind Code:
A3
Abstract:
An apparatus for transporting an optical signal is provided comprising at least two sections of optical fiber, (400 and 410) a directional wavelength selector (18) positioned between the at least two sections of optical fiber (400 and 410) wherein the directional wavelength selector (18) selectively blocks wavelengths propagating in a reverse direction, and a pump light emitting device (420) optically coupled to the optical fiber.
